Fwd: eclipse plugin

There are significant differences between 2.7 plugin at
[http://www.scala-lang.org/scala-eclipse-plugin] and the nightly
plugin for 2.8 at
[http://www.scala-lang.org/scala-eclipse-plugin-nightly].

The 2.8 release is due within a few weeks, and the nightly plugin will
then become the new standard version. You might like to try that
version instead and see if it works for you - that will put you on the
main line post-2.8. Be aware, however, that the nightly version has
its own issues; some builds work better than others.

Compile errors about semicolons are a symptom of a failed plugin installation.

They occur because the Scala plugin reuses parts of the JDT, via AOP.
When the AOP interceptions don't work properly, the JDT ends up
parsing the Scala source with a Java compiler.

The plugin certainly works (most of the time), but you will need some
determination: Uninstall all Scala plugins. Restart. Install just the
2.8 plugin. Restart. Create new Scala project with new Scala file.
Enter some code. Do you get complaints about semicolons?

Actually, yes.
i am having the parsing errors.
i am using the WTP eclipse, as i said, not the empty one even without
the java parser.
have trying installing all the versions. the offline, the update site,
the nightly...
so i have decided just to put some highlighting for it that i have
made and totally uninstall anything scala.
my eclipse has stopped that freezing of every half an hour, i can use
it normally again.
as i use ant, i compile from the command line and can use the scala.
maybe someday when i have nothing to do, i`ll download the source code
and see whats wrong with it,
had to do it for LUA once, not pretty.

just hope that some day it will work just as the XML, C++ ..... add ons

cheers anyway

Really, the nightly plugin works quite well. But I do remember that
activating the JDT Weaving was hard for me. Every time I tried to
activate it in "Preferences → JDT Weaving", in fact it wasn't really
activated (after a reboot, the checkbox was unchecked again).

At the end, I had to activate it manually, as explained here:
http://wiki.eclipse.org/JDT_weaving_features#Turning_on_JDT_Weaving_manu...

Hope it helps,

hummm
that could be it then francois. i`ll try to see whats going on
